Assume a year has passed and there has been improved security by applying a number of controls. Using the information from Table 1 and table 2 in the attached document, calculate the post-control ARO and ALE for each threat category listed.
... Table A Calculations for ALE from SLA for a Year Threat Category Cost per Incident(SLE) Frequency of Occurrence ARO ALE Programmer mistakes $5,000 1 per week ...
... What would be the budget for reducing or preventing that damage? ALE = SLE X ARO Give 1 in 3,000 of having a earthquake. ...ALE = ARO x SLE. ARO = 35%. ...
... EF) SLE = $10,000,000 * 60% = $6,000,000 Where, EF is the percentage loss that would occur from a given vulnerability exposed ALE = SLE * ARO ALE = $6,000,000 ...
